Too much stool? #orderwhat  @AFPjournal @PCareProgress @AANP_NEWS @AAPAorg


Many radiologist would not specifically comment on stool burden.  I have made it part of my practice to include "Dense stool and air filled colon, correlate with signs and symptoms of constipation" when I see a radiograph like this.

If you get a normal report and you see the colon looking like this, consider constipation.

What is appropriate medical imaging?

Having been in radiology a number of years, I know it can be difficult to decide what is the best study, if any, for each patient. Radiation? Cost? Wait time? Contrast or not? MRI vs CT scan?

The American College of Radiology teamed up with many specialist to create the Appropriateness Criteria. It has the goal of helping providers better choose which study is best for their patients.

There is terrific information in this project, however it can be intimidating to navigate.

I will summarize a few per week, with links to the source documentation, as a primer for my friends who are not necessarily radiologists.

Fellow providers, please leave comments and I will address them to the best of my ability. Patients please see below.

This is the entire Appropriateness Criteria:

This is also accessible from here:

http://www.guideline.gov/search/search.aspx?term=acr+appropriateness



Radiologists in training may benefit from these posts as well as the ABR Core Exam asks specific question from the ACR AC.

Acute pancreatitis? Ultrasound or CT? When?

#orderwhat #pancreatitis @AFPjournal @PCareProgress @AANP_NEWS @AAPAorg #choosingwisely

Imaging for acute pancreatitis

First time presentation, abdominal pain, and increased amylase and lipase with high clinical certainty of diagnosis; LESS THAN 48–72 hours after onset of symptoms; clinical score irrelevant; 
unknown cause  => US abdomen to assess for gall stones



Everything else, probably => CT abdomen with contrast, see below.  




Critically ill, systemic inflammatory response syndrome (SIRS), severe clinical scores (eg, acute physiology and chronic health evaluation [APACHE], bedside index of severity in acute pancreatitis score (BISAPS), and/or Marshall); GREATER THAN 48–72 hours after onset of symptoms. => CT abdomen with contrast

Continued SIRS, severe clinical scores, leukocytosis, and fever; >7–21 days after onset of symptoms. => CT abdomen with contrast

Initial presentation with atypical signs and symptoms, including equivocal amylase and lipase values (possibly confounded by AKI or chronic kidney disease) and when diagnoses other than pancreatitis may be possible (bowel perforation, bowel ischemia, etc). => CT abdomen with contrast


Known necrotizing pancreatic and peripancreatic pancreatitis, significant deterioration in clinical status, including abrupt decrease in hemoglobin/hematocrit, hypotension, tachycardia, tachypnea, abrupt change in fever curve, or increase in white blood cells; time
after symptom onset irrelevant. 
=> CT abdomen with contrast

Knee pain without trauma. Is there an effusion? Degenerative changes?

Imaging for knee pain without trauma. Is there an effusion? Degenerative changes?

Summary

Child, adolescent or adult knee pain without trauma = knee X-ray  

Child, adolescent or adult knee pain without trauma and knee X-ray is negative or shows effusion or secondary signs of trauma = MRI knee without contrast

Adult knee pain without trauma and knee X-ray shows avascular necrosis = possibly MRI without contrast if it directs therapy


Adult knee pain without trauma and knee X-ray shows degenerative changes, crystalline arthropathy or chondrocalcinosis = Probably NOTHING
